Make Your Own – Part 4 – Rest of Code

Make Your Own – Part 4 – Rest of Code

This is a LONG page, take time to do each bit in sections to get your head around it all. Agitation Timing This for me, was the hardest part to get my head around as I just don’t understand how millis settings work in arduinos. […]

Make Your Own – Part 3 – Main Board

Make Your Own – Part 3 – Main Board

The Theory The Arduino Mega powers the main screen, timer interface and the relays for button lights and more importantly the motor for agitation. Imagine the whole code script as a flow chart for doing things in sequence. Rough Setup Guide. For the minute, in […]

Make Your Own – Part 2 – Temp Setup

Make Your Own – Part 2 – Temp Setup

The Theory The smaller arduino uno, takes the temperatures of the two chemicals, via the DS18B20 temp sensor setup. This is then displayed on the relevant 4 digit display and updated every second. Once the chemicals reach a certain temp, then the arduino sends a […]

Make Your Own – Part 1 – Bits & Downloads

Make Your Own – Part 1 – Bits & Downloads

Here as promised is a rough overview to building a semi-automated system (And I mean rough). I must apologise as I haven’t got the time to do a step-by-step guide. In order to build this, you will need to learn some basic Arduino coding, just […]

Prototype Done, Now build your own

Prototype Done, Now build your own

Fred Dibnah, Died 2004, a personal hero of mine 🙂 Firstly, I think I must do a few apologies first to some people. As with most Internet websites/ideas, I got a bit lost off with this one in 2019, mainly due to discovering a love […]

It works!, First Test Run, with Video

It works!, First Test Run, with Video

Well after a bit of a wait for some chemicals, I decided to make a very boring 15 minute video showing the entire process of the first time using the ‘Developist’ to actually process some film. I’d recommend watching it full screen to see all […]

Motors Arrived! – Final Testing

Motors Arrived! – Final Testing

Well after about two weeks, my new motors came from China. Not bad really 2 weeks is pretty quick considering 6 motors and postage was under £6. These ones look the same as the others except the motor shaft is metal not plastic. They are […]

A QUICK TOUR OF THE PROCESS

A QUICK TOUR OF THE PROCESS

*Picture heavy post* Whilst I’m waiting for the new quicker motors for my agitation stick, I thought I’d do a quick ‘process of order’ so people can understand what the machine is trying to help with. I’ve missed a couple of steps out but it […]

Changing motor on Agitation

Changing motor on Agitation

Well initial testing of the machine is going well. I am currently sorting out timing for some common Dev processes I use and I’ve even added a buzzer to signal as well as the light when chemicals need changed etc. I realised something with the […]

Prototype Nearly Finished

Prototype Nearly Finished

Yey!, my prototype is nearly finished with the exception of auto temp starting!, well in the shed anyway. Not actually tested it with film yet. It may look a bit of a mess, but the logic is that once it’s refined, I’ll think of a […]

Control Panel – Lighty up buttons!

Control Panel – Lighty up buttons!

After my earlier post, and the realisation that not everything was going to fit, I threw all asthetic designs for a panel out the window and went with a basic but functional tupperware box lol ! My pretty light up buttons came from AliExpress as […]

Agitation – Let’s not overcomplicate

Agitation – Let’s not overcomplicate

OK, Agititation, the subject that gave me a few headaches when I started doing a fully automated version from scratch. The whole thing is now massively simplfied and just as effective. When looking over the internet, most automated agitation devices were either rotary or servo-driven […]

Main Arduino ‘Brain’

Main Arduino ‘Brain’

Now that the temperature section was more or less done, I moved back onto the main board. As mentioned, I purchased a chinese mega for the main board. And again on forums whilst asking for basic help I was constantly bombared with ‘up their own […]

Temperature monitoring – Making coding easier

Temperature monitoring – Making coding easier

Warning – long post! If your bored already, look at the bottom picture for results With my new outlook and fresh enthusiasm for the project, I thought I’d tackle the more basic issues first, temperature readings. I wanted two temp setups, one for the chemical […]

A false start – New Beginning

A false start – New Beginning

During the past month or so, as with all projects, life got in the way and more important things made it to the front of the DIY/Job list. When I finally got back on this project, a few things started to dawn on me. Firstly, […]

CONTROL PANEL DESIGN

CONTROL PANEL DESIGN

Well after deciding against building a fully automated processor (read previous article) I have decided on using the same style of control for my machine. I want it to look a bit retro, 70’s style push button kind. I started a mockup on paper (I […]

Coding – Basic Electronics

Coding – Basic Electronics

I hate coding, plain and simple. I work in IT as a Network Manager and even though we use alot of scripting for Windows, code has never interested me and I find it very boring! Sadly for this project I would need some! I settled […]
